The nozzles inpractice have e.

the wall-plate P and through which the noz- 'zles 1 project, are morethan suflicient to allow for the necessary oscillation or traverseimparted to the nozzles; and in the present especially while the boileris being blown,

suchlair tending not only to chill th tubes,

but to condense the steam employed for cleaning purposes, In the presentimprovement this exclusion of atmospheric .air is f accomplished by theflange 1 0" fo1ming'an extension ofthe outer stationary member or casing10 of the hollow joint (the member 10 constituting the inner rotatablemember of said joint), said flange being inthe nature of an a min orshield and being bolted directly to the plate-l "or apron the nozzle hasample room to oscillate, and a sliding plate mounted on the 1102- zleacross the slot, such as shown in any pendin application aforesaid isunnecessary; besides, the present improvement is much more ractical andeminently more desirable. T e flange (10") engaging the late 1? forms atight joint therewith, and likewise a chamber a'forample-accommodationof the oscillating nozzle 1. In practice ofcourse, the plate I may be dispensed with, but as it is already builtinthe walls of the majority of existing furnaces, it need not bedisturbed. In my present improve- .ment therefore, the air-excludingmember, flange or shield 'for the slot 8 is directly identified with thestationary member of the hollow swing joint. In the claims, the openingacross which the nozzle is stated to, operate, is to be'understood asthe slot sf (or its equivalent) in the plate P (or its equivalent)through which the nozzle passes and which it traverses in itsoscillations. The 'flange 10 is herein identified with the peripheralwalls of the outer joint casing 10, the ends, of the latter being closedby.

No particulanmcthod of fastening the plate I is here claimed. The plateis bent to conform to the contour of the wall-plate P and the convergingwalls of the outer portions of the window or opcningO. Refer- 'By thendriving home Vithin this shield leading through said opening, and

ring particularly .to Fig. 3, advantage is taken of the metal strips tidentified with boiler-furnaces. By bending the sheet composing theplate 'P so as to engage the outer edges of the strips t, the spring ofthe metal of the sheet will sufiice to keep the plate-P the wall-plate Pand present in existing wedged "between the strips. If necessary,

nails may be driventhrough the outer flaring portions or Wings of theplate lnto the brick-work. 'To better adjust the length of the plate I"to the heights of the openings O of different boiler furnaces, I preferto firstv place a narrow section P', at the top of the opening 4), thenlap the main section (fig.
